Definitions
- Protective clips are generally discussed herein for shielding needle tips of hypodermic needles to prevent accidental contact therewith with particular discussion extended to protective clips comprising a curved force generating section.
- Protective needle clips are well known in the art for use in conjunction with hypodermic needles.
- a typical prior art protective needle clip is mounted over a hypodermic needle.
- the prior art protective needle clip typically has a body and at least one resilient portion, which may be inherently resilient or is caused or urged to be resilient by an exterior resilient member, such as a spring.
- the hypodermic needle After an injection, the hypodermic needle is withdrawn from a body and cause to travel relative to the needle clip so that the needle clip moves from a proximal position on the needle to a distal position on the needle where the needle tip is located.
- the needle clip When the needle clip reaches the distal end near the needle tip, the at least one resilient portion is caused to move radially inwardly over the needle tip to block the needle tip.
- Other mechanisms may be incorporated with the prior art needle clip to activate the resilient portion, to launch the needle clip, or to retain the needle clip on the needle.
- prior art needle clips provide workable options for health care workers, there is a continuing need for an improved and/or alternative needle clip. Accordingly, disclosed herein are improved alternative needle clips that have a curved force generating section for biasing a different section of the clip over the needle tip of a hypodermic needle. Also disclosed are methods for using and making the same.
- the present invention provides for protective needle clips. More particularly, the present invention may be practiced by providing a protective clip for shielding a needle tip comprising an arm and a body section; the arm comprising a shielding section and a ledge and the body section comprising a proximal opening, a distal opening, and a free end.
- the free end is in contact with the ledge
- the body section comprises an arch and a resilient force capable of axially expanding the body section
- the proximal and distal openings are in alignment for receiving a needle.
- the present invention may also be practiced by providing a protective clip for shielding a needle tip comprising an arm and a body section comprising a proximal opening, a distal opening, and a free end.
- the body section being curved and comprising an arch, the free end being in contact with a ledge extending from an end of the arm, and wherein the proximal and distal openings are configured to receive a needle.
- a protective clip for shielding a needle tip comprising an arm and a body section; the arm the body section comprising a proximal opening, a distal opening, and a free end; the proximal and distal openings being in alignment and having a needle passing therethrough; the needle being in contact with the shielding section to bias the arm radially outwardly, and the free end of the body section being in contact with the ledge.
- FIG. 1 is a semi-schematic perspective view of a protective clip provided in accordance with aspects of the present invention mounted on a needle;
- FIG. 2 is a semi-schematic partial cross-sectional side view of the clip and needle of FIG. 1 with a pusher for pushing the clip;
- FIG. 3 is a semi-schematic end view of the clip of FIG. 2 taken along line F3- F3;
- FIG. 4 is a semi-schematic partial cross-section side view of the clip and pusher of FIG. 2 with the clip in an activated position;
- FIG. 5 is a semi-schematic end view of the clip of FIG. 4 taken along line F5- F5;
- FIG. 6 is a semi-schematic side view of an alternative clip provided in accordance with aspects of the present invention.
- FIG. 7 is a semi -schematic side view of another alternative clip provided in accordance with aspects of the present invention.
- FIG. 8 is a semi-schematic side view of yet another alternative clip provided in accordance with aspects of the present invention.
- FIG. 9 is a semi-schematic cross-sectional side view of the clip and needle of FIG. 1 with the clip positioned inside a pusher enclosure;
- FIG. 10 is a semi-schematic cross-sectional side view of the clip, needle, and pusher enclosure of FIG. 9 with the clip in an activated position.
- FIG. 1 a semi-schematic perspective view of a protective clip 10 provided in accordance with aspects of the present is shown mounted on a hypodermic needle 12. As shown, the clip 10 is in a pre-activated or first position on the needle 12, which is a position before the clip shields the needle tip 14.
- the clip 10 comprises a body section 16 comprising a distal opening 18 and a proximal opening 20.
- the body section 16 is curved and comprises an arch 17.
- the clip 10 also comprises an elongated arm 22, a finger 24, a tip 26, and a curve 27.
- the finger 24, the tip 26, and the curve 27 are herein occasionally referred to collectively as the shielding section 29.
- a second elongated arm 28 is incorporated.
- the second elongated arm 28 connects the curved body section 16 to the first elongated arm 22. Although shown parallel with one another, the first elongated arm 22 and the second elongated arm 28 may be non-parallel when in the position shown.
- the clip 10 shown in FIG. 1 is made by stamping an elongated rectangular strip of a thin planar sheet, such as a stainless steel sheet, stamping two openings on said stamped strip, and folding, rolling, or bending the stamped sheet into the configuration shown.
- the clip 10 is integrally formed by making a first roll or bend at the first curve 27, a second bend at the second curve 30, a third bend at the third curve 32, a fourth bend at the fourth curve 34, a fifth bend at the fifth curve 36, a sixth bend at a sixth curve 38, and a seventh bend to form the curved body section 16 of the clip 10.
- the tip 26 and the finger 24 may also be bent to form a curved tip and a curved finger.
- the bent corners may not necessarily be bent or produced in the sequence described. In other words, in an alternative embodiment, the corners can be produced in a different sequence.
- the first curve 27 and the tip 26 may be omitted.
- the curved body section 16 and the elongated arm 22 may be made by combining two or more sub-components made from a metal or a combination of a metal and a thermoplastic.
- the stamped strip for forming the clip may incorporate curves and/or notches for creating different contours and curvatures.
- the clip 10 is placed in the ready, pre-activated, or first position shown in FIG. 1 by pushing the free end 40 of the curved body section 16 behind a wedge or ledge 42 formed by the third curve 32, fourth curve 34, and fifth curve 36.
- the length of the curved body section 16 measured between the free end 40 and the fixed end 44 is longer than the length of the second elongated arm 28, which extends between the tip of the fixed end 44 and the wedge 42. Accordingly, when the free end 40 is secured ⁇ em ' ri ⁇ ' tne ' wedge 42, the curved body section 16 is compressed and resembles a loaded spring having a spring force.
- the force can vary by forming the clip from material of different stiffness, using a thicker rectangular strip, using a wider rectangular strip, adding additional curves within the arch 17 of the curved body section 16 to create multiple coiled sections, providing a large arch, and bending the curved body section 16 a greater amount.
- the ledge 42 comprises a generally flat section comprising a height extending above the second elongated arm 28 a sufficient amount to retain the curved body section 16 in the ready position.
- the height of the ledge 42 should not be so great so as to obstruct the free end 40 and prevents the free end from separating from the ledge when the clip is activated or prevent the needle 12 from passing through the two openings 18, 20.
- the finger 24 is pushed downwardly to provide clearance for the needle, which causes the first elongated arm 22 to flex radially outwardly from the axis defined by the needle 12.
- the finger 24 is biased downwardly, which requires the first elongated arm 22 to flex.
- the free end 40 is also secured to the wedge 42.
- FIG. 2 a semi-schematic side view of the clip 10 and the needle 12 of FIG. 1 is shown from a reversed angle.
- the clip 10 is shown with the second elongated arm 28 superimposed with the first elongated arm 22.
- the elongated arm 22 is flexed to accommodate the needle 12. The flexing creates an upward force at the proximal end 48 of the elongated arm near the wedge 42.
- a pusher 50 comprising a generally cylindrical body 52 comprising a proximal opening 54, a distal opening 56, and an axial bore 58 connecting the proximal opening and the distal opening is mounted on the needle 12 proximally of the clip 10.
- the pusher 50 is a means by which the clip 10 is moved from a proximal position on the needle 12 to a distal position on the needle to activate the clip 10 to then shield the needle tip 14 from accidental contact therewith.
- the clip 10 may be moved by a user's finger, a spring, or any other means capable of moving the clip from a proximal position on the needle 12 to a distal position on the needle.
- the pusher 50 is an optional device for moving the clip 10.
- the pusher 50 is molded from a hard thermoplastic, which can be any thermoplastic or plastic blend currently available on the market.
- the thermoplastic is polypropylene.
- the pusher 50 may have an opaque irj ii" 1 ' 1 " 1 Il'” ,.” Ij Ii Ij 1 "" 1 ipii Ji;;- / ..ii ";;;n .. ⁇ i u";n 101 Ji' appearance, a semf-opaque "appearance, one or more colors, and/or texture for aesthetic appeal.
- the distal opening 54 and the proximal section 57 of the passage 58 comprise a diameter measured approximately 1 to 10 mils larger than the diameter of the needle 12.
- the diameter is measured approximately 1-7 mils larger than the diameter of the needle and more preferably between 1-3 mils larger than the diameter of the needle 12.
- the distal opening 56 comprises a diameter measured less than the height of the clip 10 measured from the elongated arm 22 to the peak of the arch 17 of the curved body section 16.
- the distal opening 56, more specifically the perimeter of the opening 56 is such that when the pusher 50 is pushed against the clip 10, the perimeter of the opening 56 contacts the arch 17 of the curved body section but not the wedge 42. This permits the portion of the arm 22 adjacent the wedge 42 to rotate radially outwardly away from the axis of the needle 12.
- the distal passage section 60 of the passage 58 comprises a plurality of different diameter sections.
- the distal section 60 may have a tapered entrance section 62, a round mid-section 64, and a tapered rear section 66 that intersects the proximal passage section 57.
- the tapered entrance section 62 extends proximally and intersects the proximal passage section 57.
- the tapered entrance section 62 should incorporate an angle such that the wedge 42 on the clip 10 is able to rotate radially outwardly without being delimited by the distal passage section 60.
- FIG. 3 an end-view of the clip 10 taken along line F3-F3 of FIG. 2 is shown.
- both the distal 18 and proximal 20 openings have a generally circular projection.
- the circular opening has a circular projection.
- the opening has a generally oval or ellipse projection with the narrow portion of the oval being aligned along the vertical direction and the longer portion of the oval being aligned along the horizontal direction.
- FIG. 3 is an end view of the clip 10 taken along line F3-F3 of FIG. 2 with the clip being in the ready position, the needle 12 and the proximal opening 20 have a generally circular projection.
- FIG. 2 shows the distal opening 20 being generally circular although it is recognized that since the curved body section 16 is tilted slightly forward at the opening 20 due to the curvature of the arch 17, the projection is not a true circle.
- the proximal opening 20 of the clip 10 has a diameter of about 1-10 mils larger than the diameter of the needle 12 with the range of 1-3 mils being more preferred.
- the proximal opening 20 may have a different diameter range provided the spring force generated by the curved body portion 16, as further discussed below, is sufficiently strong to permit the opening 20 to grip lpi ij' "Ij"' _..”
- U Ij « ⁇ ;" ⁇ ii"'ii jiTM • ⁇ M ";;ii -Jj ⁇ lTMi ⁇ " 1 JjI 1 the needle" I2 '! wnen trie ' opening 20 is tilted forward to take on an oval projection.
- the distal opening 18 has a same diameter range as the diameter range of the proximal opening 20.
- FIG. 4 a semi-schematic side view of the needle 12 and the clip 10 of FIG. 2 is shown with the clip in the activated or second position.
- the clip 10 is activated by pushing the clip distally towards the needle tip 14. If a pusher 50 is incorporated, the clip 10 is pushed by the pusher 50. If there is no pusher, then the clip 10 may be pushed by a user's finger. As the shielding section 29 of the clip moves distally of the needle tip 14, the bias on the elongated arm 22 by the needle is released and the elongated arm 22 moves radially inwardly which then moves the shielding section 29 over the needle tip 14 to shield the needle tip.
- the shielding section 29 moves distally of the needle tip 14, the bias on the elongated member 22 (See, e.g., FIG. 2) is released and the elongated member 22 springs radially inwardly in returning to its normal configuration.
- the force and the momentum of the elongated member 22 separates the wedge 42 from the free end 40 of the curved body section 16.
- the separation of the free end 40 from the wedge 42 in turn releases the constraint on the curved body portion 16 and permits the curved body portion to axially expand along the length of the needle shaft 68.
- This in turn causes the distal opening 18 and the proximal opening 20 to tilt further from vertical over the needle 12. Consequently, each opening contacts the needle 12 along an upper portion and a lower portion of the opening, i.e., contact the needle at the narrow portion of the oval projection to grip the needle 12.
- the clip 10 is now activated to shield the needle tip 14 of the needle 12.
- the shape and size of the arch 17, the material of the clip, and the size of the proximal and distal openings 18, 20 are such that sufficient gripping force is generated at each opening to permit the two openings to grip the needle 12 when the clip is activated.
- the openings 18, 20 should have a grip that is sufficient to maintain the clip 10 at the end of the needle adjacent the needle tip during normal use following an injection.
- FIG. 5 is a semi-schematic end view of the clip 10 and the needle 12 taken along line F5-F5 of FIG. 4, shown without the pusher 50 for clarity.
- the curved body portion 16 expands over the needle 12 and the portion of the arch 17 at the distal opening 20 tilts forward in the direction of the needle tip. Due to the tilt, the distal opening 20 takes on an oval projection and contacts the needle 12 along the top 43 and the bottom 45 of the needle, with top and the bottom being corresponding to the top and the bottom of the page.
- the left side and the right side of the needle 12 remain spaced apart from the left side and the right side of the distal opening 20, with the left side and the right side being corresponding to the left side and right side of the page.
- the clip 70 is formed by taking a stamped metal strip and rolling the strip at a first curve 72 to form a wedge 74. Then rolling the strip at a second curve 78, third curve 80, and fourth curve 82 to form a shielding section 84, and rolling the strip at a fifth curve 86. Finally, rolling a large arch 90 to form the curved body portion 88.
- a proximal opening and a distal opening are formed on the curved body portion 88 to receive a needle, similar to the proximal and distal openings 18, 20 on the clip 10 of FIG. 1.
- An elongated arm 76 is located between the first curve 72 and the second curve 78.
- FIG. 7 is a semi-schematic side view of another alternative protective clip 92 provided in accordance with aspects of the present invention.
- the alternative clip 92 is similar to the clip 10 of FIG. 1 in that it incorporates several rolled curves from a single metal strip. However, several additional rolled curves are incorporated in the curved body section 94 to provide a curved body section with added resilient coiled affects.
- a first body curve 96, a second body curve 98, and a third body curve 100 are incorporated to produce two resilient coils 102, 104.
- the resilient coils 102, 104 provide the curved body section 94 with added biasing force for a stronger gripping force on the needle by the distal opening and proximal opening (not shown) than a comparable clip with a single resilient coil.
- FIG. 8 is a semi-schematic side view of yet another alternative protective clip 106 provided in accordance with aspects of the present invention.
- the clip is similar to the clip 70 of FIG. 6 in that it incorporates a several rolled curves made from a stamped metal strip.
- the present alternative clip 106 incorporates a first body curve 96, a second body curve 98, and a third body curve 100 on its curved body section 108 to produce two resilient coils 102, 104.
- the present clip 106 is able to produce a stronger gripping force on the needle at the distal opening and the proximal opening (not shown) than a comparable clip with a single resilient coil.
- FIG. 9 is a semi-schematic partial cross-sectional side view of the clip 10 of FIG. 1 mounted on a needle 12 and located inside a pusher enclosure 110.
- the pusher enclosure 110 surrounds the clip and is configured to deter or limit after activation contact with the clip 10 by a user.
- the pusher enclosure 110 comprises a base 112 and an elongated body section 114 made from either a semi-hard or a hard thermoplastic.
- the thermoplastic is transparent so that the clip 10 may be viewed by a user through the enclosure 110. Obviousnely, the thermoplastic may be opaque or semi-opaque.
- the base 112 comprises a proximal opening for receiving the needle 12 and is formed with either male or female detents.
- the elongated body section 114 is generally cylindrical in shape, incorporates a distal opening for rece ⁇ vi ' ng " M ⁇ 'n"i ⁇ cl ⁇ e, ahcf mcoriporates corresponding male or female detents for engaging the base 112.
- the pusher enclosure 110 and the clip 10 may be mounted over the needle 12 by first sliding the base 112 onto the needle 12 then follow by the clip 10.
- the elongated body section 114 is then slid on the needle 12 and over the clip 10 and is caused to engage the base 112 by forcing the detents on the base on the elongated body section 114 to mate.
- the enclosure 110 and the clip 10 are then pushed proximally along the needle 12 to a desired final position, which in one exemplary embodiment includes pushing the housing and the clip proximally until the base 112 contacts a needle hub.
- the pusher enclosure 110 is grasped and pushed distally over the needle 12. Once the shielding section 29 moves distal of the needle tip 14, the elongated arm 22 rotates radially to move the shielding section 29 over the needle tip 14, as previously discussed. Subsequently, the proximal and distal openings (not shown) on the curved body section 16 grip the needle 12 to prevent the clip 10 from dislodging from the end of the needle, also as previously discussed.
- the free end 40 of the clip 10 is covered or enclosed by the enclosure 110.
- the free end 40 cannot be pushed or otherwise tempered with to cause the proximal and distal openings to move from their oval projection to their circular projection and lose their grip on the needle 12.
- the elongated arm 22 incorporates a bent 111 for facilitating radial movement of the shielding section 29 over the needle tip. Note that while the clip 10 of FIG. 1 is shown located inside the pusher enclosure 110, any of the various alternative clips described elsewhere herein may be used in combination with the pusher enclosure.
- the various clips described elsewhere herein may be used to protect the needle tip of a safety spinal needle, a Huber needle, or any needle where a needle tip is desired to be shielded following an injection.
- a catheter assembly where one of the various clips described elsewhere herein is to be mounted inside a catheter hub, means for coupling the clip with the interior cavity of the catheter hub should be incorporated.
- the catheter tube is left in place while the needle and needle hub are withdrawn from the catheter tube and catheter hub.
- the clip For a clip to shield the needle tip of a catheter assembly following an injection, the clip must first be positioned inside the catheter hub and move relative to the needle when the needle is withdrawn from the catheter tube until the needle tip moves near the clip, at which point the clip must disengage from the catheter hub, shield the needle tip, and move with the needle relative to the catheter hub. Further discussion regarding how a clip operates when mounted inside a catheter assembly is described in U.S. Patent No. 6,616,630, the contents of which are expressly incorporated herein by reference.
- the means for mounting the clip described elsewhere herein with a catheter hub may include a bump, a projection, a ring, or a groove formed inside the interior cavity of the catheter hub. The highest point on the curve body section of the clip may then engage the bump, projection, ring, or groove to engage the clip to the catheter hub and to thereby permit the clip to move relative to the needle when the needle is withdrawn from the catheter tube.
- the elongated arm rotates radially, the curved body section expands axially and the highest point on the curve body section separates from the bump, projection, ring, or groove to then separate the clip from the catheter hub.
- the proximal and distal openings grip the needle to cause the clip to attach to the needle and move with the needle relative to the catheter hub.
- the clips discussed elsewhere herein may incorporate retaining wings for use with a catheter assembly.
- Retaining wings are described extensively in Ser. No. 10/677,810, filed October 1, 2003, the contents of which are expressly incorporated herein by reference.
- the retaining wings may be formed on the curved body section of the various clips for engaging the bump, projection, ring, or groove located inside the catheter hub. When incorporated, a pair of retaining wings may be positioned either adjacent the free end or the fixed end of the curved body section.
- the dimensions of the protective clip can vary depending on the particular hypodermic needle assembly used with the protective clip, the material selection can vary, the arc of the various curves can vary, and the protective clip can be made by assembling or bonding different components together instead of from a unitary construction.
- Still other changes may include using a resilient spring to advance the protective clip towards the needle tip to shield the needle tip, wedging the spring clip inside a catheter hub to be moved by the catheter hub towards the needle tip, and wedging the spring clip inside a collar of a Huber needle to be moved by the collar towards the needle tip of the Huber needle. Accordingly, many alterations and modifications may be made by those having ordinary skill in the art without deviating from the spirit and scope of the invention.
